stock market portfolio excel

I am looking for an experienced software developer to help me create an Excel portfolio to track multiple global stock markets. The portfolio should also feature real-time stock data updates of shares, bonds, etf's funds in Euros and dollars , as well as automatic calculation of portfolio performance and interactive charts and graphs. I am open to suggestions for the design of the portfolio, but any suggestions should emphasize ease of use and data accuracy. Experience in creating stock market portfolio excels is desired, and familiarity with finance and investment concepts is a plus. The developer should be prepared to provide updates on the project's progress and present demos of the portfolio as it develops. The developer should also use their expertise to suggest any possible improvements, as well as answer any related questions. I'm looking for someone who can bring professionalism and a unique approach to this project. Please contact me if you have any questions or would like to discuss further.
